    Default E30 m20b25 engine into my e34

    here goes,

    does anyone attemp this convertion b4? the b25 block that i hv from e30 doesnt seem to fit well with the mounting bracket. the holes are different in position so i cant use my e34 bracket. any ideas. i dont wanna revert back to the b20 since the engine is already out.

    it's exactly the same engine you just need to use the e34 mounting brackets, the e30 oil pan works, if you don't want to plumb in the oil cooler that the e30 uses the adaptor will be in your old block, unscrew the oil cooler adaptor and the threaded part from the old block screws right in
    all america wants is cold beer warm cat and a place to take a poop with a door on it

    thats wht i tot, but the old mounting can be screwed into the new block since its not alligned, the bracket is smaller. weird but its true.
